Evidence

For chronic SCI, GRADE confidence ratings were moderate to high for evidence showing exercise can improve all of the reviewed outcomes except bone health. For acute SCI, GRADE ratings were very low for all outcomes. For chronic SCI, there was low to moderate confidence in the evidence showing that 2–3 sessions/week of upper body aerobic exercise at a moderate to vigorous intensity for 20–40 minutes, plus upper body strength exercise (3 sets of 10 repetitions at 50%–80% 1-repetition maximum for all large muscle groups), can improve cardiorespiratory fitness, power output, and muscle strength. For chronic SCI, there was low to moderate confidence in the evidence showing that 3–5 sessions per week of upper body aerobic exercise at a moderate to vigorous intensity for 20–44 minutes can improve cardiorespiratory fitness, muscle strength, body composition, and cardiovascular risk.
